一、緩沖罐的作用
緩(huan)沖(chong)罐(guan)主要用(yong)于各種系(xi)(xi)統(tong)(tong)中緩(huan)沖(chong)系(xi)(xi)統(tong)(tong)的(de)(de)(de)壓(ya)(ya)(ya)力波動(dong),使系(xi)(xi)統(tong)(tong)工(gong)作更平穩。緩(huan)沖(chong)罐(guan)的(de)(de)(de)緩(huan)沖(chong)性(xing)能主要通過壓(ya)(ya)(ya)縮(suo)罐(guan)內的(de)(de)(de)壓(ya)(ya)(ya)縮(suo)空氣來實現(xian)。緩(huan)沖(chong)罐(guan)有(you)(you)隔膜式緩(huan)沖(chong)罐(guan)和氣囊式兩(liang)種,被廣泛(fan)應用(yong)于中央空調、鍋爐、熱(re)水(shui)(shui)(shui)器(qi)、變頻、恒壓(ya)(ya)(ya)供水(shui)(shui)(shui)設備中,其(qi)緩(huan)沖(chong)系(xi)(xi)統(tong)(tong)壓(ya)(ya)(ya)力波動(dong),消除(chu)水(shui)(shui)(shui)錘起到穩壓(ya)(ya)(ya)卸荷的(de)(de)(de)作用(yong),在系(xi)(xi)統(tong)(tong)內水(shui)(shui)(shui)壓(ya)(ya)(ya)輕(qing)微變化時,緩(huan)沖(chong)罐(guan)氣囊的(de)(de)(de)自動(dong)膨(peng)脹收縮(suo)會對水(shui)(shui)(shui)壓(ya)(ya)(ya)的(de)(de)(de)變化有(you)(you)一(yi)定(ding)緩(huan)沖(chong)作用(yong),能保證(zheng)系(xi)(xi)統(tong)(tong)的(de)(de)(de)水(shui)(shui)(shui)壓(ya)(ya)(ya)穩定(ding),水(shui)(shui)(shui)泵不會因壓(ya)(ya)(ya)力的(de)(de)(de)改變而(er)頻繁(fan)的(de)(de)(de)開啟。
二、緩沖罐的結構和工作原理
緩沖罐(guan)是利(li)用液體的(de)壓縮(suo)性(xing)極小的(de)性(xing)質,用外力(li)(li)將(jiang)液體儲存在罐(guan)內,氣(qi)體受到(dao)壓縮(suo)壓力(li)(li)升高(gao),當外力(li)(li)消失壓縮(suo)氣(qi)體膨(peng)脹(zhang)可(ke)將(jiang)水排除。
緩(huan)沖(chong)(chong)(chong)罐(guan)(guan)主要由氣(qi)(qi)(qi)(qi)門蓋、充(chong)氣(qi)(qi)(qi)(qi)口、氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)、碳鋼罐(guan)(guan)體(ti)(ti)、法蘭盤(pan)組成(cheng),當(dang)(dang)其連接(jie)到(dao)水(shui)(shui)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)上時(shi),主要起一個蓄能器(qi)的(de)(de)作(zuo)用,當(dang)(dang)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)水(shui)(shui)壓(ya)力(li)(li)大(da)(da)于(yu)(yu)(yu)(yu)緩(huan)沖(chong)(chong)(chong)罐(guan)(guan)碳鋼罐(guan)(guan)體(ti)(ti)于(yu)(yu)(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)之(zhi)間(jian)(jian)(jian)(jian)的(de)(de)氣(qi)(qi)(qi)(qi)壓(ya)力(li)(li)時(shi),系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)水(shui)(shui)會(hui)(hui)在系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)壓(ya)力(li)(li)的(de)(de)作(zuo)用下(xia)(xia)擠(ji)入緩(huan)沖(chong)(chong)(chong)罐(guan)(guan)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)內(nei)(nei),這樣(yang)一是(shi)(shi)會(hui)(hui)壓(ya)縮罐(guan)(guan)體(ti)(ti)于(yu)(yu)(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)之(zhi)間(jian)(jian)(jian)(jian)的(de)(de)氣(qi)(qi)(qi)(qi),使(shi)其體(ti)(ti)積(ji)減(jian)小(xiao),壓(ya)力(li)(li)增大(da)(da);罐(guan)(guan)體(ti)(ti)于(yu)(yu)(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)之(zhi)間(jian)(jian)(jian)(jian)是(shi)(shi)出(chu)廠時(shi)預充(chong)的(de)(de)氣(qi)(qi)(qi)(qi),罐(guan)(guan)體(ti)(ti)外面(mian)為(wei)烤漆(qi)層,進出(chu)水(shui)(shui)口直(zhi)接(jie)用三通或金屬(shu)軟管(guan)連接(jie)到(dao)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong),排氣(qi)(qi)(qi)(qi)閥接(jie)口可及時(shi)排出(chu)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)和氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)內(nei)(nei)的(de)(de)水(shui)(shui)溢出(chu)的(de)(de)空(kong)氣(qi)(qi)(qi)(qi),也可用閘閥直(zhi)接(jie)關(guan)死,以免水(shui)(shui)從頂部溢出(chu),防塵(chen)帽下(xia)(xia)面(mian)是(shi)(shi)充(chong)/放氣(qi)(qi)(qi)(qi)口,可補充(chong)氣(qi)(qi)(qi)(qi)或放掉(diao)一部分氣(qi)(qi)(qi)(qi)體(ti)(ti)。二是(shi)(shi)會(hui)(hui)增加系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)整(zheng)個水(shui)(shui)的(de)(de)容納空(kong)間(jian)(jian)(jian)(jian),使(shi)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)壓(ya)力(li)(li)減(jian)小(xiao),直(zhi)到(dao)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)水(shui)(shui)的(de)(de)壓(ya)力(li)(li)和罐(guan)(guan)體(ti)(ti)于(yu)(yu)(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)之(zhi)間(jian)(jian)(jian)(jian)的(de)(de)氣(qi)(qi)(qi)(qi)壓(ya)力(li)(li)達到(dao)新(xin)(xin)的(de)(de)平(ping)衡(heng)才(cai)停(ting)止進水(shui)(shui)。當(dang)(dang)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)水(shui)(shui)壓(ya)力(li)(li)小(xiao)于(yu)(yu)(yu)(yu)膨(peng)脹罐(guan)(guan)內(nei)(nei)氣(qi)(qi)(qi)(qi)體(ti)(ti)壓(ya)力(li)(li)時(shi),氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)內(nei)(nei)的(de)(de)水(shui)(shui)會(hui)(hui)在罐(guan)(guan)體(ti)(ti)于(yu)(yu)(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)之(zhi)間(jian)(jian)(jian)(jian)的(de)(de)氮(dan)氣(qi)(qi)(qi)(qi)的(de)(de)壓(ya)力(li)(li)作(zuo)用下(xia)(xia)擠(ji)出(chu),補回到(dao)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong),系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)水(shui)(shui)容積(ji)減(jian)小(xiao)壓(ya)力(li)(li)上升,罐(guan)(guan)體(ti)(ti)于(yu)(yu)(yu)(yu)氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)之(zhi)間(jian)(jian)(jian)(jian)的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)積(ji)增大(da)(da)壓(ya)力(li)(li)下(xia)(xia)降(jiang),直(zhi)到(dao)兩者達到(dao)新(xin)(xin)的(de)(de)平(ping)衡(heng),水(shui)(shui)停(ting)止從氣(qi)(qi)(qi)(qi)囊(nang)(nang)(nang)擠(ji)壓(ya)回系(xi)(xi)(xi)(xi)統(tong)(tong)(tong),緩(huan)沖(chong)(chong)(chong)罐(guan)(guan)起到(dao)調節系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)壓(ya)力(li)(li)波(bo)動(dong)的(de)(de)作(zuo)用。
三、壓力罐的安裝位置要求
1、農村庭院
在農(nong)(nong)村地區,我們通常用水井來使用壓(ya)力(li)罐(guan),考(kao)慮到揚程和(he)壓(ya)力(li)的(de)(de)問(wen)題,壓(ya)力(li)罐(guan)的(de)(de)位置(zhi)不應該離井太(tai)遠(yuan),但是(shi)由于(yu)農(nong)(nong)村水井邊上(shang)一(yi)(yi)(yi)(yi)般是(shi)露(lu)天的(de)(de),我們可(ke)以(yi)(yi)(yi)考(kao)慮把壓(ya)力(li)罐(guan)裝(zhuang)到離水井不遠(yuan)的(de)(de)配房里(li)面(mian),這樣我們一(yi)(yi)(yi)(yi)來可(ke)以(yi)(yi)(yi)避(bi)免風吹雨淋對壓(ya)力(li)罐(guan)上(shang)面(mian)電(dian)子器(qi)件的(de)(de)損(sun)耗,二來在房間里(li)也可(ke)以(yi)(yi)(yi)在冬天到來的(de)(de)時(shi)候更好的(de)(de)去做防凍處理。當然,以(yi)(yi)(yi)上(shang)并不是(shi)說壓(ya)力(li)罐(guan)不能在露(lu)天使用,只是(shi)如果有(you)條件的(de)(de)話,肯定屋(wu)里(li)更合適(shi)一(yi)(yi)(yi)(yi)點,如果需要露(lu)天擺放(fang)的(de)(de)話,我們可(ke)以(yi)(yi)(yi)用大(da)飲料瓶將壓(ya)力(li)開關(guan)保護一(yi)(yi)(yi)(yi)下(xia),至于(yu)罐(guan)體(ti),只要選擇304不銹(xiu)鋼材(cai)質,是(shi)完全沒有(you)腐蝕或者上(shang)銹(xiu)擔憂的(de)(de)。
2、城市使用
由于水壓不(bu)(bu)足,許多城(cheng)(cheng)市家庭將(jiang)購買(mai)壓力罐的問題被用作壓上(shang)水使用,那么(me)在(zai)這個城(cheng)(cheng)市,放(fang)哪里(li)比較(jiao)合(he)適呢?壓力罐本身的體積較(jiao)小不(bu)(bu)會占(zhan)用太多的空(kong)間,不(bu)(bu)過(guo)容(rong)量還(huan)是(shi)蠻大的,就像(xiang)家用冰箱一樣,所以我(wo)們可以安裝(zhuang)在(zai)浴(yu)室或廚房角落的一個角落里(li),因為(wei)它既不(bu)(bu)占(zhan)用太多空(kong)間,也不(bu)(bu)會影(ying)響家庭本身的裝(zhuang)飾精(jing)美程度(du),如果有單(dan)獨的儲物間的話也是(shi)不(bu)(bu)錯的安裝(zhuang)位置。
總之,對壓(ya)力罐的安裝位(wei)置(zhi)(zhi)沒(mei)有嚴格的要求。在安裝時,我(wo)(wo)們(men)還需(xu)要考慮(lv)其他(ta)一(yi)(yi)些(xie)問題,如水源(yuan)的位(wei)置(zhi)(zhi)、水泵的揚程(cheng)和水的位(wei)置(zhi)(zhi)。根據以上(shang)問題,我(wo)(wo)們(men)可以計算出一(yi)(yi)個合理的位(wei)置(zhi)(zhi)。此外,我(wo)(wo)們(men)還需(xu)要考慮(lv)天氣等(deng)原因,如冬(dong)季寒(han)冷,為(wei)了方便保(bao)溫,我(wo)(wo)們(men)需(xu)要盡(jin)量把(ba)它(ta)安裝在室內,一(yi)(yi)些(xie)人甚(shen)至為(wei)了防止冰凍而把(ba)它(ta)安裝在地下(xia)。如果購(gou)買的壓(ya)力罐壓(ya)力較小,但(dan)它(ta)們(men)使用的出水口較多,這時,我(wo)(wo)們(men)可以將安裝位(wei)置(zhi)(zhi)放高,并借(jie)助一(yi)(yi)下(xia)自然壓(ya)力。
四、家用壓力罐怎么安裝
1、放置壓力罐
我們先將品牌壓力罐側(ce)放(fang),將(jiang)(jiang)(jiang)壓(ya)力罐(guan)的(de)支(zhi)架(jia)找到,用螺絲將(jiang)(jiang)(jiang)支(zhi)架(jia)固定在壓(ya)力罐(guan)底部,再(zai)將(jiang)(jiang)(jiang)壓(ya)力罐(guan)放(fang)在水源附近(jin)的(de)位置(zhi),比如(ru)所我們(men)將(jiang)(jiang)(jiang)壓(ya)力罐(guan)放(fang)在水井旁(pang)邊。壓(ya)力罐(guan)要水平放(fang)置(zhi),不能(neng)出現傾斜的(de)問(wen)題(ti)。我們(men)在安(an)裝壓(ya)力罐(guan)時,要先準(zhun)(zhun)備好(hao)相關的(de)材料(liao)和(he)工具(ju),例如(ru)我們(men)要根據壓(ya)力罐(guan)的(de)大小準(zhun)(zhun)備好(hao)相應規格的(de)水管(guan),大家(jia)還需準(zhun)(zhun)備好(hao)止回閥、生料(liao)帶、水管(guan)接頭、水泵、熱熔機、剪刀(dao)、扳手等安(an)裝材料(liao)和(he)工作。
